Enabling high-speed computing and communications.
Some applications require intensive computing power. Some require the transfer of large amounts of data. Some require both. Keeping up with a 10Gigabit pipe can consume significant processor resources, starving the running application. Keeping up with a processor-intensive application can result in a high-speed connection being underutilized.
Technologies such as iWARP have emerged to address these issues. Through use of RDMAP (Remote Direct Memory Access Protocol) and DDP (Direct Data Placement), iWARP is designed as a zero-copy protocol. Unlike other solutions that write incoming data into a buffer, from which it is copied to application memory, iWARP writes incoming data directly to application memory. Direct Memory Access enables iWARP to create an accurate copy of the data even if packets arrive out of order.
The work is done by RDMAP-enabled Network Interface Cards (RNICs), where the intelligence in an iWARP solution is centered.
Designed to work on any network that supports TCP, iWARP can be used to accelerate processing in a supercomputing center with massively parallel processors, or to enable high-speed data transfers across the Internet or a private WAN. As a result, it must perform under typical WAN conditions, including delay, jitter, errors, packet re-order and packet loss.
With Anue Emulators, you can realistically model high-speed networks at full line rate for all packet sizes for testing iWARP implementations. |
Anue Network Emulators can reproduce with accuracy any network configuration and condition, including delay, jitter, errors, drop, reorder, fragmentation and duplication. This makes them well suited for iWARP testing. Anue offers cost-effective, scalable solutions to emulate from 1 to 64 different network profiles simultaneously at full line rate for all packet sizes.
You can use Anue Network Emulators for iWARP testing as follows:
- Characterize the true performance gain of an iWARP implementation under realistic network conditions.
- Verify iWARP technology integrity even in the presence of out-of-order packets (e.g., DDP segments arriving out of order).
- Verify error recovery capability when subjected to packet drops and bit errors.
- Verify performance throughput of an RNIC under delay, jitter and other impairments.
- Verify performance monitoring of an RNIC.
